My 3rd generation Apple TV won't let iTunes connect to it unless I unplug it and plug it back in. Apple TV is connected with an ethernet cable to a Apple extreme router and the computer is a 2011 Macbook Pro connected wirelessly. All software is up to date. I can access the macs iTunes library from the TV but can't play iTunes from the computer. When I hit the airplay icon it says connecting to Apple TV then times out eventually. However if I unplug it then plug back in the dang things connects immediately. Also have a iPhone 4 that works flawlessly as well. I also don't have any passwords set on any of the devices if that helps. Thanks
